Interop with MS extensions

[Sumit Gupta <sumit.gupta@oracle.com>]

Hi All,

Does anyone know of Microsoft's proprietary extensions introduced in WCF?

The following is in the latest version of the WSDL published by 
Microsoft for their plug-fest events.
http://131.107.72.15/ReliableMessaging%5FService%5FIndigo/ReliableOneWayDual.svc?WSDL
 
xmlns:msc="http://schemas.microsoft.com/ws/2005/12/wsdl/contract";
...
 
  <wsdl:portType *msc:usingSession="true"* name="IPing">
    <wsdl:operation *msc:isInitiating="true" msc:isTerminating="false"*
                    name="Ping">
      <wsdl:input wsa10:Action="urn:wsrm:Ping"
                  message="tns:IPing_Ping_InputMessage"/>
    </wsdl:operation>
  </wsdl:portType>

Our tools are having trouble consuming this wsdl. I wanted to know how 
others are dealing with these attributes. How do we know which ones can 
be ignored?

Thanks,
Sumit
